Apple Planning New Rapid Security Responses for iPhone, iPad, and Mac to Address Website Loading Issue

In a support document published today, Apple said it is aware of an issue where the recently released Rapid Security Responses for iOS 16.5.1, iPadOS 16.5.1, and macOS 13.4.1 might prevent some websites from displaying properly.

Rapid Security Response Feature 1
The affected Rapid Security Responses are labeled as iOS 16.5.1 (a), iPadOS 16.5.1 (a), and macOS 13.4.1 (a). Apple said new Rapid Security Responses with a (b) suffix will be available soon to address this issue. Users who do not wish to wait have the option to uninstall the (a) versions by following the steps outlined by Apple below.

iPhone or iPad: Open Settings > About > iOS Version, then tap "Remove Security Response." Tap Remove to confirm.

Mac: Choose the Apple menu > About this Mac, then click More Information. Under macOS, click the Info (i) button next to the version number. Click Remove and Restart, then click to confirm.

Rapid Security Responses are designed to provide iPhone, iPad, and Mac users with security fixes without the need to install a full software update. The updates released yesterday addressed an actively exploited WebKit vulnerability, but some users who installed the updates were subsequently unable to load some websites.

I haven't had a single problem with the (a) version and so I'm not uninstalling it... but I also don't use anything made by Meta. Perhaps I'm just lucky.

Apple should have stuck to guns and kept original version.
Would finally force websites to actually do things better.

Don't know why we need so many security updates a .1 release is good enough
Because as vulnerabilities are discovered, it's a good idea to patch them. I think that's why the framework of RSR came about. In this age of connected devices, it's much easier to attack computers.

The days of when malware were primarily transmitted by the insertion of a floppy disk into your computer are long gone. In those days, malware did not spread as fast and exploitation of a computer often required physical access. Those days are long gone as the primary mode of computer hacking.

I usually follow the rule of not updating on day 1 with the regular updates but made a mistake with this RSR. I now have learned my lesson.
